The "Download free PDF" button might require email (I didn't try it), but the "Read Online" button just pops up the doc with no further info required.
Either way, it's only $60 if you want a print copy, apparently.
Sure, but at that point isn't this nature article basically an advertisement for that report?
Isn't every Nature article an advertisement for a scientific report you might have to pay for to get in print?
It's free to read. The button is right there on their page.
I honestly didn't realize how bad this site is until I clicked around a bit and saw all the paywall stuff. I always thought they were scholarly articles, appears not.
Articles from scholarly journals usually cost money. Nature of the beast for narrow-interest publishing with no advertiser support. The fact that Nature links to the source articles is a big plus in my book.
